[PCPER] NVidia G-sync

[Gryz]

The Asus VG248QE is a lightboost monitor. It seems G-SYNC capable monitors will all be 120/144Hz monitors.

Does that mean that we will be able to use G-SYNC in combination with 2D-LightBoost ? To get zero-motion-blur in games ?

That would be a sure reason to buy a new monitor. No sync-related stuttering, and no motion-blur.

Almost certainly they will be available. Sounds great to me, just a shame I recently upgraded my monitor.

I personally doubt that Lightboost will work with this feature. Lightboost was designed for 3D, and takes a hack to use it outside 3D Vision. The way the glasses are used to get the 3D Vision effect may not be compatible, so they may not attempt to make it work in 2D.

I want to see this used on monitors above 1080p myself but I don't think native 120hz will arrive for 1440p soon. Overclocking is not the same.

I still wonder how much improvement from G-Sync was simply due to the difference between 60hz and >60hz.

I'm sure it's actually an awesome technology to reduce tearing, but 120hz already has made tearing far less noticeable for me, and as long as I keep my framerates around 80-120fps in games 120hz is completely smooth in my perception.

The real trick is if G-sync can keep gameplay as smooth as 120hz @ 120fps as say 40hz 40fps would be on G-Sync.

G-sync allows for tear free gaming without stuttering and or latency issues.

120 FPS on a 120hz monitor will be smoother than 40hz with G-sync, but 40hz with G-sync will be a lot smoother than 40hz with V-sync.

It will also have tear free FPS at 40 FPS with the same latency as 40 FPS without V-sync. It may even appear more responsive, because the whole screen gets updated, instead of part of the screen, though I'm not sure how that will translate to the responsive feel.

 

[BallaTheFeared]

Excuse me? Is this a joke? Everyone gets tearing. Unless your vision is off, i'd have to agree with others in this thread. When I turn vsync off tearing is immediately and completely obvious.

Lucid Virtu ftw.

Is nobody actually using virtual vsync? It's one of the big reasons I don't use CF that often!

I couldn't get it to work in BF3 so gave up. I really wanted it to work

I can't wait to see this in person. I always figured 120hz would solve the stuttering problems at <60fps, since the each refresh is half as long. It just isn't the case, and even worse, a shaky frame rate between 80-90fps looks far worse than 60 locked...because it clearly stutters. I've had to resort to manually changing my refresh rate to 60hz if a game cant maintain 120, just so I can keep it locked.

With G-sync, 58fps is basically just as good as 60fps. Before it becomes either a tearing mess with vsync off, drops down all the way to 30 with double buffered vsync, or stutters like crazy with triple buffered vsync. I'm much more comfortable raising graphics settings knowing that a minor dip isn't going to cause one of the above issues....and it should have perfect input lag to boot.

I think what this really needs to seal the deal though, is a game that's aware of g-sync, and has a variable strength motion blur. The amount of motion blur should be tied to the current frame rate - the lower the frame rate, the more motion blur should be applied, since there's a longer time period between frames. Done right, drops in performance would be experienced as little more than an increase in motion blur, but it should still appear super smooth to the eye, even at much lower frame rates than 60. That's going to make a constantly shifting frame rate much more palatable.

I don't think this will actually have "perfect" input lag. Input lag is as much about framerate as it is about Vsync. Higher framerates give you more responsive controls. I do think that Gsync will result in no grossly huge Vsync style input lag, but the higher the framerate you are achieving even with Gsync will result in better input.

By perfect input lag, I mean the same performance that you'd get with no vsync. Of course your frame rate is still the ultimate determinant. Even though it's not a magic bullet, there's no compromise.

so to use mantle you have to buy a amd gpu -can't have that amd only gpu.
to use gsync you only have to buy a nv gpu and a unknown quality monitor with a nv circuit board in it. that is the greatest ever.
not sure what you guys are smoking.

We're talking about the technology not how it's implemented. Big difference. Maybe you should stop seeing everything as a big fight between brands.

BTW. AMD doesn't sell "broken" products anymore. The "issues" G-sync is fixing are the common bread of every gpu and can only be fixed by using special device that works only with cuda cards (those more expensive than gtx650ti only ).

Cause only Nvidia seems to have come up with a way to make gaming smoother for their customers. This could have come from any manufacturer, but it needs to sync to the GPU to function.

 

[rgallant]

Yah its crazy that billions of people don't see things the same right. Its almost as if people are different in how they see things..
Get it through your head that people don't see tearing, at all.

I'll back you up on this

only time I have notice tearing was in SC-blacklist coming out of the map for 1-2 sec's. while the game sync'ed up.
once a week in bf3 for 1-2 sec's.

always used samsung monitors 226,2443 and now SA850.

funny alot of people here 2 years ago would warn op's not to get sli because of micro stutter , until it became a amd issue only. no issues in nv sli.
I didn't see it on 8800gts 512 sli, gtx285 sli or my 580 sli.

not saying it does not happen for people just saying ,maybe I'm so fixed on the game and don't notice it.

One major difference is Mantle will fragment gaming code further for a little extra FPS. While the extra FPS is nice, it is not something new or special. It also is going to require special coding to make it happen on every game made.

Gsync requires you to purchase a piece of hardware, either a special monitor, or the conversion kit. Once done, it works for every game that gives you the ability to override v-sync options (not sure on others).

If you want to purchase the hardware, presto, it is working.

 

[Subyman]

Hopefully they come out with a chip for 60hz monitors with higher resolutions. I'd love to install one on my Viewsonic. I wonder if any large TVs will see this tech as an option?

At certain framerates for whatever reason I notice tearing more than other times. Like anything between 60fps and 75fps is more noticeable than above 75fps. I can't explain why, it's what I see. I don't use vsync anymore due to the input lag. If this gsync stuff can really work I think it's fantastic. I just don't believe it will function with my monitor.

Problem is...I'm not buying a $700+ monitor lol.

I notice it at odd times as well - I notice tearing all the time even with vsync at times if there are large variances with respect to the framerate. It just feels "off".

I'm pretty excited to see g-sync in action. My only question is, based on the website NV has put up, only the asus 24 inch lightboost screen is compatible with the upgrade module (nvidia's wording on their G-sync website). Hopefully that selection will expand as they've indicated - I'd really like to try this out and be able to use on a high res IPS panel.

edit: erm, so is this upgrade module going to work on the overlord panels? Did I miss something?

The overlord people don't even know yet. But the fact that they were reached out to by Nvidia means Nvidia thinks it's possible, just sometime after the initial ASUS deployment.

Yeah, same here :\

I know this is off topic for this thread, but stop with the FUD. You do not know that Mantle will fragment the gaming market. The only confirmed thing I've seen about mantle is that it is compatible with D3D HLSL which is Direct X. The difference is that it skips the abstraction layer of Direct X.

If your games are coded using D3D HLSL to the metal for xbox it should in theory just work on GCN GPU's through Mantle.

I do not believe you can expect it not to be an extra fragment. It requires an additional code path on PC's. Isn't that the definition of fragmentation?

Carmack, Sweeny, and all the big names talking about, all recognize it as fragmentation, so I don't see what FUD I'm talking about.

It is fragmentation. The only question is how much support it will get, and how useful it will be.

Of course if it was a direct copy from the console version, it wouldn't require coding, but even AMD's reports say otherwise. They will be similar enough to copy chunks of code, but that is about it.
